IOS8.1 Music App won't play "Skip When Shuffling" songs at all

Question

iTunes has two options for skipping a song during shuffle:  the first column with the tick box (let's call this the "Play Column"), and the "Skip When Shuffling" tick box in the Options tab of the song info.
For songs in iTunes where the Play Column is unticked but Skip When Shuffling box is also unticked, this works as it should when synced to the iPhone:  ie the song doesn't come up in shuffle, but it can still be selected & played directly on Music app.
But when the Skip When Shuffling box is ticked (regardless of whether the Play Column is ticked or not), the song can't even be selected & played directly on the Music app.  When selected, it just picks another random song from my playlist to start shuffling from.
It's like the Skip When Shuffling option overrides the Play Column (no idea why iTunes should have two different options to do the same thing anyway), but has also now stopped the App from playing the song at all.  I've tested this by unticking the Skip When Shuffling box in iTunes & re-syncing to the iPhone, and the Music app now plays the songs when selected directly.
My iPhone 4S using iOS8 always played these songs with no problem, so this is a new issue/bug/feature with either iO8.1 or the app in the iPhone 6 itself.

Answer 1

What kind of Music App are you using?
Maybe some Apps they have bugs when using iOS7.
I'm using MVDIO and zingmp3, it's still okay here.
